Martin has officially exercised his $1.3 million player option to remain with Detroit for the 2015-16 season, Shams Charania of RealGM reports. It was presumably an easy decision for Martin, whose deal will now be guaranteed for next season. After playing sparingly in just 23 games in 2014-15, Martin likely would have had trouble finding guaranteed money elsewhere. The Kansas State product will return to the Pistons in a similar role, primarily providing wing depth off the bench.
